Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990876, here are decompositions:

67 + 990809 = 990876
79 + 990797 = 990876
109 + 990767 = 990876
157 + 990719 = 990876
233 + 990643 = 990876
239 + 990637 = 990876
277 + 990599 = 990876
283 + 990593 = 990876

Showing the first eight; more decompositions exist.
